If the depot level inspection is incapable of finding damage less than a failed load path, then the requirement for intact structure is given in JSSG-2006 paragraph A3.12.1c.  This states that initial manufacturing damage shall not grow to the size required to cause load path failure due to the application of P_LT in one design lifetime.  The initial damage assumption for this case is illustrated in Figure 1.3.16.  The schematic of the growth and residual strength guidelines are illustrated in Figure 1.3.19.
